Hypar (Hyperbolic Paraboloid)
This model, representing a hyperbolic paraboloid, is thought to originate from the paperfolding experiments at Bauhaus in the late 1920’s. However, details of its authorship remain unknown, making it an example of a relatively modern traditional model. This design is an example of achieving the effect of a curved surface by folding a set of straight lines.
